Oscillators

The 550ME155M520DG oscillator is a precision timing device that offers high accuracy, reliability, and stability over a wide range of temperature and shock conditions. While designed primarily for use in embedded systems, such as routers, switches, and embedded servers, the 550ME155M520DG is also suitable for applications that require precise timing control. This includes industrial, medical, and consumer applications, where timings can be highly inaccurate due to environmental variables.

The 550ME155M520DG oscillator has a miniature package with a 5.0 mm size, making it suitable for space-constrained applications. The onboard crystal is constructed to absorb shock and vibrations effectively. The machine uses a two-stage frequency-selective, auto-tuning, oscillator design. This ensures that the oscillation frequency remains constant even when subjected to temperature changes or vibration. It also ensures that a high level of accuracy is maintained over the lifetime of the device.

The 550ME155M520DG also features ‘Resistive-Ratio’ error correction technology. This function checks and corrects the frequency of the oscillator output as it fluctuates due to the thermoelectric effect. To further enhance accuracy and stability, the oscillator also offers a wide range of temperature frequencies. These range from -40°C to +85°C (±5%), +105°C (±6.5%), and +125°C (±7.5%).

The 550ME155M520DG oscillator includes a wide range of features. It has an acceleration sensitivity of 50 g, an acceleration of 2 g, a temperature drift of 100 ppm, and a frequency offset over temperature of 1000 ppm. The frequency error is very low, at 5 ppm over the entire operating temperature range. The operating voltage range is 3.3 to 5.5V, with a total power consumption of less than 150 μA. Furthermore, the frequency stability of the oscillator over the lifetime is ±100 ppm.

The 550ME155M520DG oscillator is designed for use in embedded systems and other applications that require precise timing control. Its minimized size makes it suitable for space-constrained applications. Its frequency accuracy and stability ensures that the oscillator maintains a constant frequency even when subjected to temperature changes or vibration. Its acceleration sensitivity of 50 g, acceleration of 2 g, and temperature drift of 100 ppm makes it highly reliable and precise. The frequency error over temperature is only 5 ppm, while its frequency stability is ±100 ppm. All these features makes it an ideal solution for embedded applications.
